Threats affecting pkg:github/Plausible Analytics

Plausible Analytics through 3.2.1 contains a mass assignment vulnerability in update_traffic_change_notification that allows authenticated site editors to reassign notifications by supplying a site_id parameter. Attackers can submit traffic_change_notification[site_id] set to another site's primary key via PUT /sites/:domain/traffic-change-notification/:type to receive that site's traffic alerts and visitor figures.

Plausible Analytics Community Edition through 3.2.1 contains an information exposure vulnerability that allows site editors to obtain pending invitation and ownership-transfer IDs from the settings/people page. Attackers can register with the invitee's email using the exposed ID and accept it, gaining the invited role or taking site ownership.
